AI data centers face infrasound complaints; inaudible low-frequency noise escapes decibel regulation

Neighboring communities around AI data centers are filing complaints about infrasound (low-frequency, below-hearing-range noise) that causes physical discomfort but does not register on decibel meters used in local noise ordinances. The gap between what meters measure and what residents experience is creating regulatory blindspots and tension between operational continuity and community relations.

For data-center operators, this signals emerging environmental liability around low-frequency emissions from cooling and power distribution. Proactive acoustic modeling and noise-mitigation specs during site planning and phased ramp-up can avoid costly retrofits and community opposition.
